 detail of wavenumber-5 patternThe crippling wintertime droughts that struck California from 2013 to 2015, as well as this year's unusually wet California winter, appear to be associated with the same phenomenon: a distinctive wave pattern that emerges in the upper atmosphere and circles the globe.
 an Argo float being deployedThe oceans may be storing 13 percent more heat than previously estimated, according to a new study co-authored by scientists at NCAR.
 CESM forecast for last quarter of 2016An NCAR-based computer model known for global climate projections decades into the future recently joined a suite of other world-class models being used to forecast what may lie just a few months ahead.
NCAR Senior Scientist Martyn ClarkNCAR hydrologist Martyn Clark named AGU fellow; his research includes developing new modeling methods for streamflow forecasts.
 summer weather map of USThe ratio of record highs to record lows will increase sharply if greenhouse gas emissions continue.
North American temperature trends for 30 members of the CESM Large EnsembleThe CESM Large Ensemble reveals a staggering range of Earth climates that could have been along with a rich look at future climates that could potentially be.
 ocean map shows Pineapple Express patternA high-resolution climate model based at NCAR is able to accurately capture the ribbons of moist air that sometimes escape the sodden tropics and flow toward the drier mid-latitudes, allowing scientists to investigate how "atmospheric rivers" may change as the climate warms.
Sulfates could limit global warming - image illustrates volcano plumeIf society doesn't make steep cuts in greenhouse gas emissions in the next few decades, how much injection into the atmosphere of planet-cooling sulfates would it take to limit warming to 2 degrees Celsius above preindustrial levels?
Mount Pinatubo's caldera on June 22, 1991Greenhouse gases are already having an accelerating effect on sea level rise, but the impact has so far been masked by the cataclysmic 1991 eruption of Mount Pinatubo in the Philippines.
Image of Antarctic sea ice in 2014The recent trend of increasing Antarctic sea ice extent — seemingly at odds with climate model projections — can largely be explained by a natural climate fluctuation.
